I've seen a bunch'a different "cover-ups" to try to mask this problem. My own home has 2-3 layers of drywall in 3 rooms. Why they added the weight I'll never know. I do NOT recommend that! In other houses I've seen texture so thick that it started falling off in large chunks in the kitchen. 1x strips and another layer of drywall. Plywood and then another layer of drywall.
The best way to fix this is replacement.
